Figure 3 I In the embodiment of the invention shown in Figuresl to 12, a casing 1 is provided, of

suitable size and formation, the said casing having its top rounded, as shown in Figure 2, and within this casing there is mounted to rotate adrumcomposed of a shaft 2, and a pair of heads 3 secured to the shaft, the

heads being near the ends of the'casing. A seriesof chart rollers i 15 mounted between the'headsto move with the heads, and the rollers. are journaled in the heads to move independently of the rotative movement of the drum. :The rollers 4 are mount- :ed atthe peripheries of the head, their axes being in acylinder'whoseaxis is the shaft 2.-

Each ofthesechart rollers hasat each endahead 5,- 'thesaid heads being extended through the ends of the casing, and by means of the heads the cylinders may he rotated 'Each cylinder bears-upon its-peripheral isurfaceidata toibe-f described, and re fei-ringito-Figure'1 ,"it will be seenthat the 5 ends of the casing 1, near thet0p,"are offset inwardly, so'that while the heads 5. project 1 beyond the said ends, they are within the planes of the ends of the casing. i 2- Each head 5 of each chart roller is connectedtothe roller by a stem,'or axial journal pin 6,-and each ofthese pins 6 is engaged by tensi( )ningmcchanism shown in Figuref), The said. tensioning mechanism compr1ses a sprlng f wire or the like, having one end securedto the end'of the casing, as indicated at 8, and the other end iscurved to engage about the stem or ournal pin, as shown, to exert-a tensioning-or braking action on the movement of the chart roller.

These chart rollers are adapt-ed to be brought in succession into observing position at a longitudinally extending slot or passage 9 in the front of the casing 1,'the said slot orpassage being enlarged laterally at its ends, asshown-at 10 in Figure 1, and preferably anenlarging lens, indicated at 11, is supported over this slot or passage, the said lens being designed to magnify the data on the chart roller, so that it will be clearly visible through the slot or passage.

An auxiliary casing 12 is arranged at the left end of the casing 1, the shaft2 extending into this auxiliary casing, and a pinion 13 issecured to thelshaft within theauxiliary 'casingi' The'auxiliary casing has its frontmcurved,.as shown'in Figure .3, and

the teeth of the pinion 13 are engaged by the teeth of an arc-shaped rack bar 14-, which is secured to one face of a disk 15, which has an eccentric hub 16 journaled on a pivot pin 17, which pivotally connects the disk to the auxiliary casing.

The hub 16 has oppositely extending pins 18, which are journaled in the arms of a fork 19 on one end of a lever 20, which eX- tends between a pair of lugs 21 at the periphery of the disk, and at one end of the rack bar lat. This arrangement permits the lever to swing laterally longitudinal of the hub, while at the same time the disk may be rotated by swinging the lever circumferentially with respect to the hub.

A coil spring 22 is arranged between the lever and the disk, and this spring acts normally to press the lever away from the disk. The free end of the lever extends out through a slot 23 in the auxiliary casing 12, the said slot extending circumferentially of the hub 16, and one edge of the slot has notches 2 1 which are adapted to be engaged by a catch lug 25 on the lever, to hold the lever in adjusted position. The lug 25 may be easily released from the notches by swinging the lever toward the opposite side of the slot or passage.

An indicator 26 is arranged transversely of the lever, just outside the auxiliary casing, and the ends of the said indicator c0- operate with scales arranged at opposite sides of the slot or passage 23, to be later described.

A rack bar 14 is coaxial with the shaft 17 and when the hub 16 and the disk 15 are rotated by the swinging of the lever, the pinion 13 will also be rotated through the engagement of the teeth of the rack bar 14 with those of the pinion 13, and the drum will be rotated. The notches 24 are so arranged with respect to the chart rollers, that when the catch lug 25 is in engagement with a notch, a chart roller will be in register with the slot or passage 9 of the casing. The movement of the lever one notch will move the drum a distance such that another chart roller will be brought into observing position beneath the opening 9.

Just above the opening 9, and extending parallel therewith, there is provided an un dercut guideway 27, in which are movable indicators, one of which is shown in Figure 12. Each of these indicators consists of a block 28, which forms a finger piece for manipulating the indicator, and to each block there is secured a slide 29, fitting the guideway, and extending transversely of the block.

The indicator proper is a metallic strip 30, secured longitudinally of the block on the face adjacent to the slide, and extending beyond both ends of the block, and the ends of the strip are pointed as shown. One end of the strip 30 cooperates with the indications on the chart rollers, and the other end, which is bent at an angle to the body of the strip, as clearly shown in Figure 2, cooperates with an indicating roller 31, journaled above the guideway.

This roller 3]., which is polygonal in cross section, has journal pins which are jouri'ialed in upwardly extcndii'ig bracket lugs 32 from the top of the casing. At that end remote -from the auxiliary casing 12, the roller 31 has a pinion or gear wheel 2-33, and this pinion is adapted to be engaged by rack bars 3 1 secured to that head 3 oi the drum which is remote from the auxiliary casing 12.

These rack bars 31 are in the form of plates, which are secured over mortises or recesses 35, in the periphery of the head 8 and at the outer face thereof. The outer edge of each rack bar is formed onan arc whose center is the axis of the drum, and the rack bars are so arranged that they will engage the pinion after a certain predetermined number of chart rollers have passed the roll 31. The arrangement is such that the roll 31 will be given a rotative movement through a predetermined arc at predetermined moments, and the chart rollers are so arranged with respect to the rack bars 3 1, and the rack bars and the roller 31 are so geared together. that the roll 31 will be turned a distance sullicient to bring another face into operative position, when a predetermined number ot chart rollers have passed the opening 9 in the case 1.

Referring to Figure 1, it will be seen that a head 31 is secured to the sh att oi the indicating roll 31, between the pinion 33 and the adjacent) bearing. This head has four sides, the corners being rounded, and it is adapted to engage the disk 3 at that end, to lock the indicating roll against accidental turning. Thus when the drum is rotated to bring another series oil rollers into observing position, the rounded corners of the head 31 may turn by ordering the inortise 35 adjacent to the rack plate 34-, thus permitting the indicating roll to turn. As soon however as the corner of the head is out of the mortise, the indicating roll is locked, and cannot turn until another mortise is brought to the head, that is until another rack bar engages the pinion 33. It will be understood that the shape of the head corresponds to the shape in cross section of the indicating roll. That is in a four sided roll, the head will be four sided. In the present instance, the roll 31 is square in cross section, that is, it has four faces, the chart rollers are 16 in number, that is, there are 41- chart rollers for each face of the indicating roll 31. The rack bars 34 are so arranged that the indicating roll will be rotated a quarter turn four tlmes during a complete rotation of the V Vals, and extending above and below the opening 9, and above the guideway 27 in which the indicating slides move. The faces of the indicating roll 31 are provided with similar guiding lines 37 which register withthe lines36. r i

Referring to Figure 6, it will be seen that between the lines-36 before mentioned, there is provideda series of other lines 38, alternating with the lines 36', and these lines38 have at each end arrow heads, as shownI Between the lines 36 and 37, there ispro vided on the faces of the roller 31, series of numerals, a series being arranged at each end of each face, one "series being indicated at A and the other at E. I11 the present instance, the fourffaces of-the roller 31 may bedistin'guished by the letters A, B, C, D atoneend, and 13,13, G, H, at the other end. The numerals on the face A -Eare for the first series multiples -of five, commencing with 5. and ending with 50. At theother end, there are also multiples of. 5, commencing with 10 and ending with 60. 'Aboye the series A is arranged alegendreading Rate in centsper 100 lbs, or'units for left hand unit sights. (28). The legend at the right of the face reads Rate in cents per hour, day and week. For pay rolls.

It will be understood that each face bears diiferent numerals and different legends, and this matter may be whatever desired. As, for instance, on face BF of the indicating roll might be carried Rate in dollars per 100 lbs, and in this instance there would be but a single series of numerals, the numerals representing dollars. A scale of this character would be especially desirable for tobacco handlers.

In Figure"? there is shown the face of one of the chart rollers 4. Each of these rollers on its peripheral surface is provided with circumferenti ally extending lines 39, dividing the said surface into ayseries of columns or-zones. Within these zones there is arranged series of numerals 40. In the roller shown in Figure 7, at the left side edge, there is a series of numerals running consecutively from 49 to 96, and in the columns adjacent thereto there is arranged a series of numerals which bear certain relations to the series 40 and to the adjacent series on the face of the roll 31. That is, in that column above which is the numeral 5011 the roll 31, there is arranged adjacent to each member of the series 40 a series of numerals which is the product of the numeral 5 b the series of numerals in the series 40, which is immediately to the left. As, forinstance,

the series of numerals '49 has in line therewith, reading from left to right .02, which is the product of 49 by .5, omitting the decimals after the second place.' In the third column from the left, in line with the series of numerals 49 there is arranged the amount .05, which is the product of 49 by .10, the tenth of cents being omitted. Beneath the numeral 50 on the roll 31 at the top of the last column. under series A, there is found the product .25, which. is the product of .49 by. .50. This computation is carried out for all of the amounts in the series 40. I

" On :the. four chart rollers, which correspond to the faces A-E of the roll 31, the

numerals in series 40 run onthe first rollerfrom 1 to 48, on the second rollercfrom 49 to 96, on the third roller from 97.to 144, on the fourth roller from 145 to 192. Those rollers which correspond to the face A E ofthe roll31 carry at the right a series '41 of numerals, and those series of numerals in the adjacent columns are products of these numerals in series 4.1 with those numerals at the head of the columns on the. roll 31, at the right end of the said roll. T i It will beobvious that any arrangement of numbers might be used inflcolurnns 40 and 41 and at the headsof the columns on the-roll 31. and that the products might be either niulti'plications. divisions, subtractions or additions. The indicators 28 are designed to point out the products particularly at the passage 9. If, for instance, it is desired to obtain the product of 50 X .25, the'indicator 28 is moved until the upper end thereof points to the numeral .25. The lower end will point at the numeral .12, which-is the product of 50 X .25. That indicator 28 at the right of the passage 9 cooperates with the scale under E and with the series 41 of numerals at the right of the chartrollers. It will be understood that the chart rollers of each series are complementary, the matter upon each being supplementar to that upon the others.

In Figure 8 there is shown the matter which is arranged adjacent to the slot or passage i There is arranged adjacent to this passage, and adjacent to the notches 24, indications permitting the. desired chart roller tobe properly arranged at the opening 9, by means of the lever 20. Referring to this figure it will be seen that the face ofthe auxiliary casing 12 at the slot is proranged legends and pairs oi. numerals. At the heads of the vertical columns, there are arranged legends as followsz-From right to left,

Rate right side of box.

Hours and days, right side of roll.

A. right on bar, "Llin. 59, hfax.

Lbs, leiit side ot roll. lVithin the squares beneath this legend there is arranged at the left, the numerals 1 to .23, 49 to 96, and the like. That is, matter indicatin the rolls which will be at the opening 9, when the lug of the lever 20 is in engagement with the adjacent notch.

In operation, when it is desired to find any product, as, for instance, the cost of 192 lbs. of some commodity at 50 per hun dred lbs, the lever 20 is grasped and moved downwardly in the slot 23, until. the indicator 26 of the said lever points at that space which bears the numerals 1415492. The fourth roll of the first series of chart rollers will now be at the opening 9, and the said chart roll carries at the lett in series so, the numerals M5 to 192. Now the operator grasps the indicator 28 and moves it until the upper end thereof registers with the numeral 50 in series A. Looking at the lower end of the indicator in passage 9 there will be found the numeral .96, this being the cost of 192 lbs. of the commodity at 50 per hundred lhs. It will be understood that a notch 24 is provided for each chart roller, and when the lug 25 of the lever 20 is in engagement with the said notch, the particular chart roller will be at the opening; 9. It will be evident that any matter desired might be provided upon the chart rollers, the proper indications being arranged adj acent to the slot 28 andv on the indicating roll. Every time the last of a series Oil rollers passes the opening- 9, a bar-3a will engage the pinion 33, and the indicating roller will be given a quarter turn. It will be evident that any number of series of chart rollers might be used, as, for instance, in Figures 13, 14- and 15 there is shown a construction wherein the indicating roll 42 is pentagonal in cross section, having five :tacesinstead of four. There are provided also 20 chart rollers, indicated at 43. the said. rollers being arranged in series of tour, and there being five series, one series of four for each face of the pentagonal roll.

The case 44 is similar to that shown in Figure 1. having the sight opening, the in dicators 4L5 and the like. The rollers 43 are journaled at their ends in bearing lugs 4L6 on endless chains 47, vhich are supported by sprocket wheels l8 and 4-9, the chart rollers connecting the chains at each end of the case. These sprocket wheels 41:8 and 49 are secured on the shafts 50 and 51, which are journaled in the case, and the indicating roll 42 has a pinion 52 at one or both ends,

which is adapted to be engaged by rack bars 52) secured to one or both oil the chains. These rack bars are arranged. between the series of "tour rollers in such manner that as the last roller of a series passes away from the opening 9, a rack bar will engage the pinion and will move the pentagonal roll a distance oi? 72. That is, a. distance sufiicient to expose another face of the roll.

The shatt 51 carries at that end adjacent to the operating lover a pinion 54;, and this pinion meshes with a larger pinion 55 journaied on the disk 56, which corresponds to the disk 15 of Figure 3. A controlling lever 57, corrcspoiuling in all respects to the lever 20 0t l igure 3 and similarly mount-ed, is connected iththe disk for operating same, carries an arc-shaped rack bar and the dis] 58, which meshes with the pinion 55. \Vhen the lever 57 is moved, the pinion 54 will be rotated through. the rack bar and pinion 55, and the wheels 49 will be moved a sufficient distance to advance another chart roller to the sight opening.

Each of these rollers 43 is provided at that end adjacent to the lever 57 with a head 59 tor (OIlYtlllOTllfG in rotating the same. The construction is otherwise the same as that shown in Figure 1, and the matter on the rollers 4:3 and, on the roll 42 and on the case is similar to that above described for the embodiment of the invention shown in Figures 1 to 12.

A locking device for. the indicating roll similar to that shown in Figure 4 is provided tort-he construction just described. This mechanism comprises a head 42 which is secured to the shaft 01 the indicating roll l2 between the pinion 52 and the ad acent bearing, and since the indicating roll has 1 five faces the head has five sides. The sides of this head 42 bear upon the adjacent endless chain 4:7, thus holding the indicating, roll 4-2 in the proper position. \Vhen the roll 42 is turned to co-operate wit-h a new set of chart rollers, the corner of the head 4:2 engages within a link of the chain and is turned. The rack bars are so placed that the corners of the head will engage within the link during the turning. This locking device insures the proper placing of the indicating roll and the proper holding oi: the said roll while the series of charts pertaining to that face of the roll exposed is being used.

It will be evident from the description that each chart ioller carries products which are arranged in rows extending longitudinally of the roller and extending circumferentially thereof, the products in each row having a common factor, the chart roller carrying the common factors of the longitudinally extending rows, while the common factors of the circum'ferentially extending rows are arranged on the roll.

ber of days say 15, and to a-given amount on the co-operating chart roller say $100.00, the lower left hand indicator will show the amount of interest on the $100.00 for 81K months, and the right hand indicator. willv show the amount of interest on $100.00 for 15 days. i

It will beunderstood that a series of chart rollers may be constituted of any. number that maybe required to carry a series of charts, and the indicating roll 31 has a face 7 to cosoperate with each set of rollers. It is obvious also that when but a single series of chart rollers are used, but one face of the indicating roll is required to be used. The provision of the arrangement shown in Figure 13 permits a great number of chart rollers to be used without making the machine too bulky.

The several parts of this maehine may be made of any suitable material and the relative size and proportion and the details of construction may be modified as may be found desirable, without departing from the spirit of the invention as set forth in the claims. w A
